For practical purposes, do you plot all NAT tracks into the plot?
Yep, we plot our random route and the daily tracks using Jeppesen plotting charts, we also change to TRUE heading for the crossing, this was something that doesn't appear to be a common practice in the corporate world (based on my CAE/FSI recurrent training)
As we use Iceland as an enroute alternate, its quite feasible that we will turn and cross more than one track.
